Publishers Weekly Rowling proves that she has plenty of tricks left up her sleeve in this third Harry Potter adventure, set once again at the Hogwarts School for Witchcraft and Wizardry. Right before the start of term, a supremely dangerous criminal breaks out of a supposedly impregnable wizards' prison; it will come as no surprise to Potter fans that the villain, a henchman of Harry's old enemy Lord Voldemort, appears to have targeted Harry. In many ways this installment seems to serve a transitional role in the seven-volume series: while many of the adventures are breathlessly relayed, they appear to be laying groundwork for even more exciting adventures to come. The beauty here lies in the genius of Rowling's plotting. Seemingly minor details established in books one and two unfold to take on unforeseen significance, and the finale, while not airtight in its internal logic, is utterly thrilling. Rowling's wit never flags, whether constructing the workings of the wizard world (Just how would a magician be made to stay behind bars?) or tossing off quick jokes (a grandmother wears a hat decorated with a stuffed vulture; the divination classroom looks like a tawdry tea shop). The Potter spell is holding strong. All ages. (Sept.) Copyright 1999 Cahners Business Information.

School Library Journal Gr 4-8-Isn't it reassuring that some things just get better and better? Harry is back and in fine form in the third installment of his adventures at Hogwarts School of Witchcraft and Wizardry. His summer with the hideous Dursley family is cut short when, during a fit of quite understandable rage, he turns his Aunt Marge into an enormous balloon and then runs away. Soon, it becomes quite apparent that someone is trying to kill him; even after Harry is ensconed in the safety of fall term at Hogwarts, the attacks continue. Myriad subplots involving a new teacher with a secret, Hermione's strangely heavy class schedule, and enmity between Ron's old rat, Scabbers, and Hermione's new cat, Crookshanks, all mesh to create a stunning climax. The pace is nonstop, with thrilling games of Quidditch, terrifying Omens of Death, some skillful time travel, and lots of slimy Slytherins sneaking about causing trouble. This is a fabulously entertaining read that will have Harry Potter fans cheering for more.-Eva Mitnick, Los Angeles Public Library Copyright 1999 Cahners Business Information.
